Inline difference

Paste two versions to compare them.

Quick Tool Overview

Text Compare puts two versions side by side and highlights every word that was added or removed, inline. A word-level comparison is what prose needs — a line diff marks a lightly edited paragraph as one changed line, which tells you nothing about what actually moved.

About the Text Compare

A line diff tells you a line changed. A word diff tells you which three words changed in it, which is what you actually want when the two texts are prose rather than code — a paragraph that has been lightly edited shows as one changed line and ten unchanged words, and only the second reading is useful.

This compares two texts at word level and highlights the result inline: additions in green, deletions struck through in red, everything unchanged left alone. It is the view you want for checking an editor's changes to a draft, spotting what a client altered in a contract, or confirming that a translation update touched only what it should have. Whitespace, case and punctuation can each be ignored, which strips out the differences that do not matter.

Key features of the Text Compare

Word-level, not line-level

A lightly edited paragraph shows only the words that moved, instead of the whole line turning red.

Proper LCS comparison

Unchanged words stay aligned, so one inserted phrase does not mark everything after it as changed.

Ignore what does not matter

Whitespace, case and punctuation can each be excluded, separating real edits from a reformatting pass.

Change counts

Words added, words removed and the percentage changed, so you can tell a copy-edit from a rewrite at a glance.

Nothing is uploaded

Both versions are compared in your browser, which is what unpublished drafts and contracts require.

Frequently asked questions

A line diff marks a whole line as changed if any part of it differs, which is right for code and nearly useless for prose. This compares word by word, so a lightly edited paragraph shows only the words that actually moved.
